Abstract: The 1987 spin-retrodiction puzzle by Vaidman, Aharonov, and Albert - the King's problem - was realized in the form of a quantum-optical analog. Success probabilities that exceed, in each channel, the single-qubit optimum were achieved. Furthermore, the mean king's second challenge, in which unitary polarizations changes are performed, was successfully implemented.
